What is the problem this feature would solve?

Making requests with Cypress is not type-checked (neither the request nor the body), making it difficult to work with.

External documents/projects?

• Cypress request
• Cypress custom commands

What is the feature you are proposing to solve the problem?

It would be great if a plugin for Cypress was created that would allow generation of commands that accept only the right request body, and return a Chainable<Response>.

Something like :

// CypressPetCreateRequest.ts

namespace Cypress {
   interface Chainable {
      createPetRequest: (body: CreatePetRequestBody) => Chainable<CreatePetResponse>
   }
}

What alternatives have you considered?

For now I'm using cy.request directly.
